    Answer:

    Sine and cosine

    Explanation:

    Velocity is a vector, so it can be resolved into two components into two perpendicular direction.

    Generally, we take the x- and the y- direction of the cartesian plane.

    If call v the velocity vector, then the components of the velocity along the two directions are:

    v_x = v cos \theta\\v_y = v sin \theta

    where \theta is the angle between the direction of the velocity and the x-axis.

    Therefore, the resultant velocity can be found from its components by re-arranging the two equations above:

    v=\frac{v_x}{cos \theta}\\v=\frac{v_y}{sin \theta}

    Therefore, the two functions that are used are the sine and the cosine.
